The TQ9 Single Board Computer

The TQ9 single board computer is a graphics-class, PICMG® 1.3 SBC that supports a variety of multi-core Intel® processors. TQ9 I/O interface capabilities include an audio codec interface, two eSATA connections to a PICMG 1.3  backplane and a dozen USB interfaces.

The embedded Intel® Q35 MCH and Intel® ICH9DO ICH deliver advanced features such as 1333MHz system bus and SATA RAID. Plugging the TQ9 single board computer into a PICMG 1.3 graphics-class backplane enhances system design flexibility.  A system designed with the TQ9 supports option cards from x16 PCI Express to legacy 32-bit/33MHz PCI cards.

Key features of the TQ9 single board computer include:

  • Supports long-life, multi-core Intel® Core™ 2 processors in a PICMG 1.3 form factor
  • Dual-channel DDR2-800 memory interface with 8GB system memory capacity
  • Excellent price/performance solution for dual or quad-core applications
  • PICMG 1.3 SBC with SATA II RAID, Video, USB, Audio, Gigabit Ethernet ports
  • Excellent processing power, extended-life processor availability, I/O features
The TQ9 single board computer maximizes ROI with long-life, embedded components which drive an extended SBC product availability of seven years or more.  As with each of our single board computers, the TQ9 is designed with a standard BIOS version that is maintained under strict revision control.

However, BIOS flexibility is built in by offering various BIOS modifications that may be needed to meet unique system requirements and maintains strict revision control for custom BIOS variations. The TQ9 is designed, manufactured and supported in the U.S. and is covered by our exclusive five-year factory warranty.
